How to appeal a Champaign County property tax assessment

Champaign County Board of Review accepts assessment complaints from July 1 to September 10. HomeTaxChallenge verified that window on the Champaign County Board of Review site — the 2026 window closed September 10, 2026. Check with your assessor or the Board of Review for the next year's dates before filing.

Steps

1. Look up your Champaign County parcel to confirm the PIN, township and current assessment.
2. Confirm the 2026 filing deadline and complaint form directly with the Champaign County Board of Review.
3. Choose a basis: overvaluation (recent comparable sales) or equity (similar assessed values). Non-farm residential property in Illinois is generally assessed at one-third of fair cash value.
4. File the complaint and evidence with the Board of Review before the deadline. The next level is the Illinois Property Tax Appeal Board (PTAB).
